Application filed May 15, 1915. Serial No. 28,305.

To all whom it may concern:

Be it known that 1. PETER VJ. Srnncunn, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Electric-Lighting Fixtures; and I do hereby declare that the following; is :2 full, clear, and

- exact description thereof.

My invention consists in what is herein particularly .set forth with reference to the accompanying drawings and pointed out in the claims of this specification, its object being to facilitate the insulation and hanging of electric-lighting fixtures by simple, economical and eflicieni. means.

Figure 1 of the drawings represents a partly sectional elevation of insulating means in accordance with in; invention applied in Como ction with the canopy of an electric-light fixture and an attaching screw, which screw is shown in engagement with a support in a. ceiling, and Fig. 2, represents a horizontal section on the plane indicated by line 2-2 in Fig. 1.

Referring by numerals to the drawings, 3 indicates a ceiling or Wall box into which a conduit 4 for electric-current distribution wires 5 and 6 extends. Screw threaded on a nipple 7 in the box is a cap 8 engaged by a suspending screw 9 for a block 10 preferably of indurated fiber or other suitable insulating material that is shouldered t have fit in a canopy 11 such as is common with electric-light fixture. The insulatingblock is partly.counterborcd to provide for the seating therein oi" a sleeve 12 of indurated fiber or other suitable insulating: niaterial through which the suspending screw 9 extends, and said block is provided with opposite longitudinal passages for the wires 5 and 6 aforesaid. The insulating-block is also provided with opposite lateral recesses with which pivot-branches 13 of a. hangerlinlrlc of an eleetric-light fixture engage. However it is within the scope of my in vention as herein claimed to otherwise adapt said block for the connection therewith of an electric-light fixture according to the demands of the trade.

The block and sleeve aforesaid combine to form an insulating fixture-loop by which to do away with the usual insulating joint with a. ceiling or wall connection, and an insulating ring on the canopy. It is also to be noted that the block of my insulating loop has two wire passages instead of one, and that said loop is centrally fastened to Support by a single screw central thereof.

Tl e block 10 may be of other than ir ulating' material when used on lathe and pl: ster work, brass, for instance, being" suitable for the purpose. The sleeve therewith is always of insulating material.

claim:

1. An electric-lighting fiXt-ureloop comprising a canopy 1.. ins; centrally counterbored bloc-ls: of insulating material throu which to exicnd an attaching-screw provided with. passages for current distri bution wires. together with screw insul. inp" sleeve seated in the counterbore of block.

An electric-lighting fixture-loop comprising a. canopyu ittin g block of insulaiti material having a central bore througgh which to extend an attaching-screw, passages :tor current distribution wires and recesses for pivot-ends of a hanger; and a screwdnsulatin5: sleeve extending from. the block.

3. An electric-lighting fixture-loop C0111 prising a centrally cunterborcd canopy itting block through which to extend an a taching-screw and provided 'ith passages for current distribution wires, together with a. scrcw-insubiting: sleeve seated in the counterbore of said block.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of lililwaukce and State of Wisconsin.

PETER N. SPR-ECHER.
